/* ============================================================================
   AVH Studios — Studio Launcher
   The "choose your studio" hub reached from the Dashboard. Visually echoes the
   in-app wizard intro (animated grid / glow / scan backdrop + equalizer) and the
   four studio cards are large, animated, clickable tabs.
   §218 — the four cards were re-imagined as clean, modern "glass tile" cards
   (Concept B): flat dark panel, top-lit hairline, a floating 3D emblem tile with
   an accent glow, an editorial 01–04 badge, minimal copy and a cursor-driven 3D
   tilt. The hero, backdrop, equalizer, nav and footer are unchanged.
   Loaded after brand.css.
